300'00 I think ummm it's right
Answer: 235.5 feet
Step-by-step explanation:
In this case, we have to calculate the circumference of the track. The circumference will be calculated as:
= 2πr
Diameter = 75 feet.
Radius = 75/2 = 37.5 feet
Circumference = 2πr = 2 × 3.14 × 37.5 = 235.5feet
Answer:
It would be the last one!! Hope this helps
Daniel made an error in line 3. He wrongly divided the sum of sides and height. The area of the trapezoid is 42 cm².
<h3>What is the area of the trapezoid?</h3>
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides.
Area of a trapezoid = 1/2 x (sum of the lengths of the parallel sides) x height
- Line 1: A = 1/2 x (6) + (7 + 7)
- Line 2: A = 1/2 (6) (14)
- Line 3 : 3 x 14
- Line 4 : A = 42 cm²
